Methods, systems, and devices related to a method of controlling an autonomous vehicle, in particular, an autonomous diesel-engine truck are disclosed. In one example aspect, the method includes determining an available engine brake torque generation mechanism for reducing a current speed of the autonomous vehicle to a lower speed and selecting a brake mode corresponding to the engine brake torque availability. In case a rate of speed reduction is equal to or smaller than a threshold, the brake mode includes only an engine brake in which engine exhaust valve opening is adjusted for reducing the current speed. The threshold determined in part based on the available engine brake torque, gear position of the transmission, and the online estimated vehicle longitudinal dynamic model. In case the rate of speed reduction is greater than the threshold, the brake mode incudes a combination of the engine brake and the foundation brake.

A control device and a method for controlling a vehicle powertrain to overcome, or avoid, a cog-to-cog condition during gear shifting is provided. The method comprises, when an input shaft of the gearbox is rotating, controlling a synchromesh arrangement so as to induce a difference in rotational speed between a first gear wheel and a first coupling sleeve arranged to lock the first gear wheel to a main shaft of the gearbox by at least partly engaging the first gear wheel or a second gear wheel to the input shaft. Furthermore, a computer program, a computer-readable medium and a vehicle are provided.

A vehicle control device executes a traveling control that controls traveling of an own vehicle to enable the own vehicle to follow a preceding vehicle traveling in front of the own vehicle. The vehicle control device includes: an environment prediction unit that predicts whether an adverse-effect change has occurred in a surrounding environment around the own vehicle, the adverse-effect change being likely to have an adverse effect on a fuel economy of the own vehicle; and an acceleration control unit configured to execute a prediction control that enables an acceleration of the own vehicle to be limited when the environment prediction unit predicts that the adverse-effect change has occurred in the surrounding environment.

A system for a vehicle trailer includes a function block having a data input configured to receive gear shift signals of a vehicle towing the vehicle trailer. The function block includes a controller configured to generate a torque increase request signal depending on a received gear shift signal of the gear shift signals, and a data output configured to output the torque increase request signal to an electric motor controller of at least one electric drive of the vehicle trailer.

A vehicle powertrain component includes a thermal transfer surface that transfers thermal energy out of a powertrain component and a thermally active material disposed over the thermal transfer surface. The thermally active material includes a variable thermal conductivity and an actuator coupled to the thermally active material induces changes in the thermal conductivity of the thermally active material. A controller governs operation of the actuator to adjust the thermal conductivity of the thermally active material responsive to a vehicle operating condition to maintain the powertrain component within a predefined temperature range.

A hybrid vehicle includes: an engine; a battery; a power converter; a relay; a first controller; and a second controller. The second controller is configured to control the engine and the power converter according to allowable charging power and allowable discharging power received from the first controller. The second controller has, as control modes, a normal mode in which the relay is closed and the battery and the power converter are electrically connected and a batteryless drive mode in which the relay is opened to cause the hybrid vehicle to move with the battery electrically disconnected from the power converter. The second controller is configured to select the batteryless drive mode when at least one of the magnitude of the allowable charging power and the magnitude of the allowable discharging power become smaller than a first predetermined value.

A display device for a vehicle includes: an image display unit configured to display a direction indicating image that indicates a travel direction of the vehicle; and a control device configured to execute travel control of the vehicle. The direction indicating image is switchable between a first image that indicates a first travel direction of the vehicle and a second image that indicates a second travel direction of the vehicle, the second travel direction being opposite to the first travel direction. In a case where the control device switches the travel direction of the vehicle from the first travel direction to the second travel direction, the image display unit switches the direction indicating image from the first image to the second image based on a vehicle speed of the vehicle, a state of a power transmission device, and a steering state of the vehicle.

A parking support system of a vehicle, comprises: a detection unit configured to detect information of a periphery of the vehicle; a control unit configured to control, based on the information detected by the detection unit, a parking space entry operation of the vehicle to a parking space and a parking space exit operation of the vehicle from the parking space; and a stationary state control unit configured to maintain a stationary state of the vehicle after one of the parking space entry operation and the parking space exit operation has been completed. The stationary state control unit maintains the stationary state by first maintenance control when the parking space entry operation has been completed and maintains the stationary state by second maintenance control, which is different from the first maintenance control when the parking space exit operation has been completed.

A travel control apparatus of a self-driving vehicle having a drive power source and a transmission installed in a power transmission path from the drive power source to drive wheels. The travel control apparatus includes a vehicle class detection part detecting a size class of a forward vehicle and a microprocessor. The microprocessor is configured to perform controlling the drive power source and the transmission so as to follow the forward vehicle, recognizing a vehicle type of the forward vehicle in accordance with the size class detected by the vehicle class detection part, and the controlling including controlling a speed ratio of the transmission in accordance with the vehicle type recognized in the recognizing.

A prime mover and a method for operating a prime mover are disclosed. The prime mover, which may be a tractor, includes a drivetrain and is configured to attach to an attachment. The drivetrain includes at least one drive motor, a gearbox, at least one power take-off, and at least one ancillary unit. The prime mover has a driver assistance system that controls the drivetrain and that includes a computing unit, a memory unit, and an input/output unit. The driver assistance system comprises an engine droop governor that works based on a characteristic curve, wherein the engine droop governor is configured for optimized control of the drivetrain depending on selectable control strategies saved in the memory unit and/or optimization target variables.
